This application claims priority to U.S. Provisional Patent Application Ser. No. 62/909,191, filed Oct. 1, 2019, the entirety of which is hereby incorporated herein by reference for all purposes.

BACKGROUND

Some mobile electronic devices, such as smart phones and tablets, have a monolithic handheld form in which a display occupies substantially an entire front side of the device. Other devices, such as laptop computers, include a hinge that connects a display to other hardware, such as a keyboard and cursor controller (e.g. a track pad).

SUMMARY

Examples are disclosed that relate to operating a user interface of a multi-screen computing device. One example provides a computing device, comprising a first portion comprising a first display and a first touch sensor, and a second portion comprising a second display and a second touch sensor, the second portion connected to the first portion via a hinge, the hinge defining a seam between the first display and the second display. The computing device is configured to receive a touch input at the first display moving an application that is currently displayed on the first display and not on the second display toward the second display, detect the touch input releasing the application within a predetermined area, span the application across the first display and the second display such that a portion of application content is hidden behind the seam, receive a touch input moving the spanned application, and move the spanned application in a direction of the touch input to reveal at least a portion of the application content hidden behind the seam.

Another example provides a computing device, comprising a first portion comprising a first display and a first touch sensor, a second portion comprising a second display and a second touch sensor, the second portion connected to the first portion via a hinge, the hinge defining a seam between the first display and the second display, a logic device, and a storage device holding instructions executable by the logic machine. The instructions are executable to receive a touch input at the first display moving an application from the first display toward the second display, when the touch input releases the application within a first predefined area, to move the application to the second display, and when the touch input releases the application within a second predetermined area, to span the application by displaying the application across the first display and the second display.

Another example provides a method enacted on a computing device, the computing device comprising a first portion comprising a first display and a first touch sensor, and a second portion comprising a second display and a second touch sensor, the second portion connected to the first portion via a hinge. The method comprises displaying a first application on the first display, displaying a second application on the second display, receiving a touch input at the first display moving the first application toward the second display, detecting the touch input releasing the application within a predetermined area, and stacking the first application over the second application on the second display based at least upon the touch input releasing the application within the predetermined area.

DETAILED DESCRIPTION

The disclosed examples relate to a computing device having a multi-screen configuration. FIG. 1 shows an example multi-screen computing device in the form of a dual-screen computing device 100. The computing device 100 includes a first portion 102 and a second portion 104 that respectively include a first display 106 and a second display 108. A hinge 110 arranged between the first and second portions 102 and 104 allows the relative pose between the portions and their displays to be adjusted. The computing device 100 may be configured to determine the relative pose between the first and second portions 102 and 104 (e.g. via motion sensor data from one or more motion sensors in each portion), and adjust a function of the computing device based on the relative pose.

Each of the first display 106 and the second display 108 may be a touch-sensitive display having a touch sensor. The touch sensor(s) may be configured to sense multiple sources of touch input, such as a digit of a user and a stylus manipulated by the user, and may sense multiple concurrent touches. The computing device 100 may assume any suitable form, including but not limited to various mobile devices (e.g., foldable smart phone, tablet, or laptop).

The first portion 102 includes a first three-dimensional pose sensor system 114 configured to provide output indicative of a three-dimensional pose of the first portion 102, and the second portion 104 includes a second three-dimensional pose sensor system 116 configured to provide output indicative of a three-dimensional pose of the second portion 104. In some examples, the first and second pose systems 114 and 116 each includes an accelerometer and a gyroscope, and optionally a magnetometer. The output produced by the first and second pose systems 114 and 116 may be used to determine a three-dimensional pose of first and second portions 102 and 104, respectively. In other examples, any other suitable sensor or sensors may be used to sense the relative orientations of the displays, such as an optical or mechanical encoder incorporated into the hinge.

FIGS. 2-5 show various example display poses for the dual-screen computing device 100. More specifically, FIG. 2 shows a single portrait pose (in which either display 106 or 108 may face the user), FIG. 3 shows a double portrait pose, FIG. 4 shows a single landscape pose (in which either display 106 or 108 may face the user), and FIG. 5 shows a double landscape pose. Depending on a pose of the computing device 100, a user interface of the computing device 100 may be configured to operate in a certain manner and/or respond to touch inputs differently. For example, in FIG. 2 and FIG. 4, the second portion 104 may be folded via the hinge 110 behind the first portion 102, or vice versa. From the perspective of a user of the computing device 100, when the second display is folded behind the first portion, the second display 108 may be imperceptible. As such, the computing device 100 may render graphical content that was previously displayed across both the first display 106 and the second display 108 fully onto the first display 106, may cease displaying images on the second display 108, and/or may also cease receiving touch inputs on the second display 108. Various examples of operating a user interface and responding to touch inputs based on the pose of the computing device are further described below.

In some examples, a touch input may span an application across both a first display and a second display of a dual-screen device. FIGS. 6A and 6B show an example user interface displayed when spanning an application 600 across the first display 106 and the second display 108 of the first portion 102 and the second portion 104 of the dual-screen device 100. First, the user interface at 602 shows application 600 open on the second display 108 of the second portion 104, while the first display 106 on the first portion 102 is unoccupied by any applications. At 604, the user interface shows that a touch input 606 has dragged the application 600 from the second display 604 toward the first display 602. The touch input 606 may originate at a location along an application navigation bar 608 that is displayed at the bottom of the application 600. The application navigation bar 608 may be configured to receive user inputs related to moving, dismissing, or otherwise manipulating the application 600. The touch input 606 may release the application 600 when the application 600 is in a predetermined area, e.g. within a threshold distance from a seam 610 in between the two displays (as defined by the hinge 110 that connects the two device portions). Example predetermined areas for triggering certain user interface actions are discussed in more detail in regard to FIGS. 12-17.

The user interface at 612 shows the application 600 spanned across both displays in response to the touch input releasing the application 600. A mask may be applied to a rendering of the application in a location corresponding to the seam 610 when the application is spanned. Such masking may help the display of the spanned application (and also application windows moving across the seam) to appear more natural, as opposed to splitting the full image between the two displays. However, such masking also causes a small area of the displayed application to be unviewable. As such, a user may desire to reveal the content being blocked by the seam. FIG. 6B at 614 and 616 show example interactions in which a user moves the application 600 (e.g. by touching and dragging) to reveal content hidden by the seam 610. Any suitable touch inputs may trigger offsetting of the application to reveal content behind the seam 610. As examples, a touch input may swipe, touch and drag, or perform a multi-finger gesture to the left or right from the seam, from a seam corner, etc. in double portrait mode. The same touch inputs may apply except in up or down directions from the seam in double landscape mode. At 614, the user interface shows a touch input moving the application toward the left, and at 616, the user interface shows a touch input moving the application toward the right. The spanned application may thereby be moved in a direction of the touch input to reveal at least a portion of the application content hidden behind the seam. In either example, a user may then move the application back to the original spanned mode shown at 612, such as by tapping a revealed arrow user interface control 618 or 620 (shown at 614 and 616), or by dragging and releasing the application back toward the seam. In other examples, such masking may not be applied, and instead the application may be divided into two portions that together make up the entire image. In yet other examples, such a seam between multiple displays may not be present, or a seam may also be configured to display content (e.g. via a flexible display over the hinge).

In some examples, a touch input may move an application while scaling the application simultaneously. FIGS. 7-9 illustrate an example of the scaling of a displayed application in response to a user touch input dragging the application. As shown, an origin of the scaling of the application may be set dynamically by horizontal touch position. For example, FIG. 7 shows a touch input 700 that starts at a right bottom corner of the application, FIG. 8 shows a touch input 800 that starts at a middle of the bottom of the application, and FIG. 9 shows a touch input 900 that starts at a left bottom corner of the application. In these examples, the scaling decreases based upon a vertical movement distance from the bottom of the display, and an origin of the movement is based upon the initial touch location of the touch input. The dynamic positioning of the origin of scaling may help to create the effect that the application follows the user's finger or stylus. The automatic scaling that occurs with movement of an application may help to better indicate to the user that the application is currently being moved while keeping the content of the application visible. Further, once released, expansion of the application back to its original size may also help to better indicate to the user that the application is no longer being moved by user input. Automatic scaling when moving an application may further help provide a more seamless transition of the application to a recent applications list or task switcher for switching between applications, as examples. For example, a preview for a recent applications list may be triggered when a gesture velocity for moving application drops to within a threshold velocity close to zero.

In some examples, an application may be moved in response to a horizontal movement and scaled in response to a vertical movement in portrait poses, and moved in response to a vertical movement and scaled in response to a horizontal movement in landscape poses. Further, the ratio of movement of the touch input to movement of the application on the user interface may change as a function of touch position. FIG. 10 shows a plot of an example vertical movement of an application on a display as a function of touch position in a Y direction when the display device is in a portrait pose. In this example, the position of an application follows a user's touch in a 1:1 ratio from a Y position of pixel 720 to pixel 400. Next, from a Y of touch from pixels 400 to 100, the change in Y position of the application compared to the change in touch location varies at a ratio of less than 1:1 from pixels 400 to 200. From Y of touch at pixels 100 to 0, the Y position of the application versus the touch position linearly varies at even a lesser ratio. In other examples, any other suitable mapping of touch movement to application movement may be used.

Likewise, the application scaling also may change as a function of touch position. FIG. 11 shows a plot of an example application scaling as a function of touch position in a Y direction. From Y of touch at pixels 720 to 400, the application may scale linearly at a first rate from 100% to 30% scale; from Y of touch at pixels 400 to 300, the application may scale linearly, but at a lesser rate, from 30% to 20% scale; and from Y of touch less than 300, the scale of the application may remain at 20%, thus not decreasing further. In the depicted example, movement of the application in a horizontal direction while in a portrait mode may follow the user's touch in a 1:1 ratio at all positions of X, and horizontal movement may not cause the application to scale, as an example. Movement of an application in a landscape mode also may display movement rate and/or scaling adjustments.

In double portrait and double landscape poses, movement of the applications from one display to the other display may be accompanied by hint images that are displayed to indicate how an application may move or behave based on the touch input. FIGS. 12 and 13 show example hint images 1200 and 1300 that may be displayed while moving an application in a double portrait pose and a double landscape pose, respectively. The illustrated example hint images indicate that if a touch input currently dragging the application were to be released at the current location, then the application would snap to or move to the display on which hint image is displayed.

FIGS. 14-17 show example hint images displayed based on touch inputs moving an application to within example threshold distances. In these figures, a transition zone 14 occupies a portion of the first display, and a portion of the second display. FIG. 14 illustrates an example in which a touch input drags an application from the second display toward the first display. In this figure, a first fraction 144 of the application, as defined from a left edge of the application to example line A, has not passed a first boundary 145 of the transition zone 14, and no hint images are yet displayed, indicating that if the touch input were to release the application at that position, the application would be displayed again at the original position without any movement.

FIG. 15 shows the application having been moved sufficiently far such that the first fraction 144 of the application has passed the first boundary 145 of the transition zone 14. In response, a hint image is displayed on the first display, indicating that the application will move to the first display upon release. FIG. 16 shows that the application has been moved so that a second, larger fraction 146 of the application, as defined from a left edge of the application to example line B, passes the first boundary 145 of the transition zone 14, and in response a hint image is displayed spanning both displays, indicating that the application will span across both displays upon release. FIG. 17 shows that the application has been moved so that the second, larger fraction 146 of the application passes a second boundary 147 of the transition zone 14, and in response a hint image is displayed on the first display, indicating that the application will move to the first display upon release. As such, there may be more than one predetermined area to which an application may be moved to trigger a same action.

FIG. 18 shows an example hint image displayed in response to a touch input moving an application to a display currently occupied by another application. In this example, a touch input moves the application from the second display toward the first display, but the first display is already occupied by another application. Upon dragging the application a certain threshold distance (such as those shown in FIG. 15 and FIG. 17) or to a certain predetermined area, the other application on the left may slightly shrink and become greyed out as a hint image indicating that the dragged application would stack on top of the other application upon release and potentially cause the other application to close in some examples.

FIG. 19 shows an example hint image displayed in response to a touch input to swap applications. Here, the application has been dragged such that the first portion 144 of the application has passed an example swapping threshold line labeled as line C. Alternatively, the application may be dragged such that a far edge 1902 of the application passes the first boundary 145 into the transition zone 14. In response to either occurrence, a hint image is displayed showing the second application on the left at a smaller scale, and further showing the second application as a greyed out image on the second display, indicating that the application on the right will swap with the application on the left upon release. It will be understood that in some examples, hint images may not be displayed, but the same actions upon release within the predetermined areas may be applied regardless of whether hint images are displayed. Further, other suitable hint images may be used in other examples.

As mentioned above, in some examples, when a first application is moved from a first display to a second display that is already occupied by a second application, the first application is stacked on top of the second application. In some such examples, the second application may remain behind the first application indefinitely in a suspended state, until the first application is either moved away or dismissed. In other such examples, the second application may be dismissed automatically. In yet other examples, the second application may remain stacked behind the first application for a predetermined threshold amount of time, after which the second application may be dismissed and may then be accessible from a recent applications list. Within that threshold amount of time, a user may undo the stacking in order to reveal and resume the second application again. FIG. 20 shows an example user interface while stacking an application and then unstacking the application within a threshold time. At 2002, Application 1 is on the left display, and Application 2 is on the right display. At 2004, a touch input moves Application 2 toward the left display onto Application 1, and Application 1 is shown smaller and transparent, as an example hint image indicating the stacking and possible application dismissal At 2006, Application 2 has been stacked on top of Application 1. However, before a threshold amount of time has passed, a touch input moves Application 2 back toward the right display, as shown at 2008, thereby revealing Application 1 before it is dismissed. After the threshold amount of time, the dismissed application may be resumed again from a recent applications list, for example. Any suitable threshold time may be used. In some examples, the threshold time may be between five and twenty seconds, and may be ten seconds in a more specific example. Further, in some examples, an application that has become stacked underneath another application may instead (either immediately or after a predetermined threshold of time) be automatically transferred to a recent applications list for retrieval by the user.

In some examples, a user may trigger the launch of a new application from a currently open application, or a new instance of the same application. When in double portrait or double landscape mode, the new task may automatically be launched from the first application for display on the display opposite the first application, if that display is unoccupied.

In some instances, the user may attempt to launch a new task from a currently opened application when the opposite display is already occupied. FIG. 21 shows an example user interface depicting launching a new task from a link in an application while another application is open on another display. At 2102, the left display is occupied by Application 1 which contains a link, and the right display is occupied by Application 2. At 2104, the user clicks on the link, which launches a new application, Application 3. Because the adjacent display is occupied, the new Application 3 opens on the same display as Application 1, stacking over Application 1 and suspending Application 1, as shown at 2106. Application 1 may be displayed as if it is receding and/or shrinking as Application 3 launches and expands to cover the left display. At 2108, Application 3 has been stacked on top of Application 1. In this instance, the stacking may not result in the automatic dismissal of Application 1. Application 1 may be restored, for example, by user retrieval from a recent applications list, as mentioned above, or by a user touch input dismissing or moving Application 3 to the adjacent display.

Similarly, moving and spanning applications may behave differently depending on whether the display(s) are already occupied. FIGS. 22-26 show various examples of spanning, stacking, swapping, and dismissal of applications in response to movements of one application when one or more display(s) are already occupied by one or more other applications. FIG. 22 shows an example user interface depicting spanning of an application over another application and then contracting of the spanned application, thereby restoring the application beneath the spanned application. At 2202, Application 1 is displayed on the first display, and Application 2 is displayed on the second display. At 2204, a user touch input moves Application 1 toward the seam, and releases to span Application 1 across both displays, stacking Application 1 over Application 2 on the second display, as shown at 2206. At 2208, a user touch input contracts Application 1 and moves Application 1 back to the first display. At 2210, Application 2 is revealed and restored.

FIG. 23 shows spanning and contracting an application when another application is open on another display, and also shows different outcomes as a result of contracting Application 1 to different screens. At 2302, Application 1 is displayed on the first display, and Application 2 is displayed on the second display. At 2304, Application 1 is shown spanned across both displays, e.g. after a touch input dragging and releasing Application 1 near the seam, thereby stacking at least a portion of Application 1 over Application 2 on the second display. The user may contract Application 1 back toward the first display, restoring Application 2 on the second display, as shown at 2306. Alternatively, the user may contract Application 1 toward the second display. Rather than stacking Application 1 over Application 2, Application 1 may be automatically swapped with Application 2, such that Application 2 is displayed on the first display, as shown at 2308. In other examples, swapping may be triggered when contracting a spanned application by moving the spanned application to a “swap threshold area” within an outer edge of the display, e.g. as illustrated in FIG. 19. If the contracted application is released outside of the swap threshold area, it may result in permanent stacking.

FIG. 24 shows spanning and contracting of an application when two other applications are stacked on another display. At 2402, Application 1 is displayed on the first display, and Application 2 is displayed on the second display while stacked over Application 3. At 2404, a user touch input moves Application toward the seam, and upon release, Application 1 spans across both displays, stacking over both Application 2 and Application 3 on the second display, as shown at 2406. At 2408, a user input contracts spanned Application 1, but depending on which side Application 1 is contracted to, the result is different. At 2410, Application 1 is shown contracted to the first display, restoring the original arrangement. However, as shown at 2412, when the spanned application is contracted at the second display where the stacked applications were originally located, the stacked applications swap locations with the spanned application. As mentioned above, in other examples, swapping may be triggered when contracting the spanned application to a “swap threshold area” within an outer edge of the display, and stacking may result when the spanned application is released outside of the swap threshold area.

FIG. 25 shows spanning and contracting an application when a second application is stacked behind the application, and a third application is open on another display. At 2502, Application 1 is stacked over Application 2 on the first display, and Application 3 is displayed on the second display. At 2504, a user touch input moves Application 1 toward the seam. Application 1 is thereby spanned across both displays, stacking over both Application 2 on the first display and Application 3 on the second display, as shown at 2506. When the spanned application is contracted, at 2508, the application may stack above either the second application or the third application, depending to which side the application is contracted. At 2510, Application 1 is contracted to the first display, restoring Application 3 on the second display. At 2512, Application 1 is contracted to the second display, revealing Application 2 on the first display while Application 1 is stacked over Application 3 on the second display.

FIG. 26 shows spanning and contracting an application when a second application is stacked behind the application, and two other applications are stacked on another display. At 2602, Application 1 is stacked over Application 2 on the first display, and Application 3 is stacked over Application 4 on the second display. At 2604, a user touch input moves Application 1 toward the seam. When Application 1 is spanned, as shown at 2606, Application 1 remains stacked over Application 2 on the left display, and further stacks over Application 3 and Application 4 on the right display. A user touch input then contracts Application 1, at 2608. When the user contracts Application 1 back to the left display, at 2610, Application 1 stacks back over Application 2 on the left display, while Application 3 and Application 4 remain stacked on the right display. In contrast, when the user contracts Application 1 on the right display, as shown at 2612, Application 1 stacks over Application 3, dismissing Application 4. This may occur, for example, if a setting dictates that only two applications may be stacked on a display at any time (other than when spanning). In other examples, more than two applications may be stacked at a time per display.

FIG. 27 shows an example method 2700 of operating a dual screen computing device. Method 2700 comprises, at 2702, displaying a first application a first display, and at 2704, displaying a second application at a second display of the dual screen computing device. Method 2700 further includes, at 2706, receiving a touch input at the first display opening a third application while the first application is displayed on the first display, e.g. from a link within the first application. At 2708, method 2700 comprises displaying the third application as being stacked over the first application. At 2710, method 2700 includes receiving a touch input closing the third application, and in response, closing the third application and displaying the first application on the first display. The computing device may open new applications from currently running applications based on whether any application(s) are already open on either of the first display or the second display.

FIGS. 28A-E shows another example method 2800 of operating a dual-screen computing device, and more particularly illustrate various methods of displaying an application based upon the application being moved to different predetermined areas of the displays. Method 2800 includes, at 2802, receiving a touch input at the first display dragging the first application from the first display toward the second display. In some examples, this may include receiving the touch input at an application navigation bar (e.g. displayed at a bottom, side, or other suitable location on the display, as illustrated in FIG. 6). While the first application is being dragged, a size of the first application may be scaled based at least in part on a direction of movement of the touch input, at 2804. At 2806, method 2800 includes displaying a hint indicating where the application will move based at least in part on the touch input dragging the first application to within a predetermined area. For example, hint images indicating that the first application will be spanned, moved, swapped, or stacked may be displayed indicating a result of the movement of the first application based on the touch input dragging the first application if the touch input is completed.

From 2802, method 2800 may continue to 2808 of FIG. 28A, or to FIGS. 28C, 28D, or 28E, which illustrate different outcomes depending on where the first application is released.

For example, method 2800 may include, at 2808, detecting a touch input releasing the first application within a first predetermined area. This may include, at 2810, detecting the touch input releasing the first application within a threshold distance of a seam of the computing device in a hinge region of the device. In other examples, such a seam may not be present. At 2812, method 2800 includes spanning the application across the first display and the second display, such that a portion of application content is hidden behind the seam. Spanning may include, at 2824, applying a mask to a rendering of the first application in a location corresponding to a seam in between the first display and the second display. In other examples, an image of the first application may be divided such that the full image is split between the two displays.

Further, spanning may include, at 2816, stacking a portion of the spanned, first application over a second application on the second display, where a second application is open on the second display.

Continuing with FIG. 28B, method 2800 further includes, at 2818, receiving a touch input moving the spanned first application. Method 2800 also includes, at 2820, moving the spanned application in a direction of the touch input to reveal at least a portion of the application content hidden behind the seam. Further, method 2800 includes, at 2822, receiving a touch input moving and contracting the spanned application to either one of the first display and the second display, and displaying the first application on one of the first display and the second display based on the touch input. For example, a drag-and-release touch input or a fling gesture may contract the first application toward the first display, and the first application may be moved to the first display in response. In instances where the first application was stacked over the second application, moving the first application may reveal the second application, as indicated at 2824. As another example, the touch input may contract the first application onto the second display, such that the first application remains stacked over the second application, as shown at 2826, thereby potentially leading to the closing of the second application in some examples, e.g. immediately or after a threshold amount of time. As yet another example, the touch input may contract the first application onto the second display, such that the first application swaps positions with the second application, instead of stacking on top of the second application, as indicated at 2828.

Where the touch input is released in a different area than the first predefined area, a different result may occur than spanning. For example, FIG. 28C shows, at 2736, detecting the touch input releasing the first application within a second predefined area. In response, as indicated at 2832, the first application is moved to the second display, instead of being spanned across both displays. Such an action also may result from a fling gesture in which a touch input is moved from one of the first and second display toward the other of the first and second display with a velocity greater than a threshold velocity, and/or an acceleration greater than a threshold acceleration, also as indicated at 2830. Moving the first application to the second display may include, at 2834, stacking the first application over a second application on the second display. In some examples, the computing device may close the second application after a threshold amount of time of the first application being stacked over the second application, as shown at 2836. This may allow a user to move the stacked first application back to the first display to reveal the second application on the second display before the second application is closed. Thus, method 2800 further includes, at 2838, receiving a touch input moving the first application back to the first display, and in response, displaying the first application on the first display. Where the first application was stacked over a second application and moved within a threshold amount of time, this also may include displaying the second application on the second display.

In another example response to the touch input received at 2802, FIG. 28D shows, at 2842, detecting the touch input releasing the first application within a third predefined area, and swapping the first application on the first display with the second application on the second display. As yet another example response to the touch gesture of 2802, FIG. 28E shows, at 2842, detecting the touch input releasing the first application within a fourth predefined area, and closing the first application in response. The touch input may drag-and-release the first application in any other suitable predetermined areas to trigger other corresponding actions, such as moving an application to a recent applications list, etc.

FIGS. 29A-B shows an example user interface depicting interactions with an applications folder in a double portrait mode of the dual-screen device 100. At 2902, the user interface shows a pinned applications bar 2904 on the first display 106 of the first portion 102, and a pinned applications bar 2906 on the second display 108 of the first portion 104. The user interface at 2902 also shows a touch input 2908 tapping an applications folder 2910 on the first display 106 display. At 2912, the applications folder 2910 is opened on the first display 106. The open applications folder 2910 may be at least partially transparent, such that content behind it is still visible. Further, the pinned applications that were on the pinned applications bar 2904 on the first display 106 are shifted over to the pinned applications bar 2906 on the second display 108. In some examples, the shifting may be animated so that a user views the transition of the pinned applications to the other display. It will be understood that shifting of the pinned applications may occur in any instance where an application or system component (e.g. a folder) occupies either screen in a dual-display mode. At 2914, a touch input 2916 performed on the second display 108 drags from left to right on the second display 108, which moves the items displayed behind the applications folder 2910 on the first display 106 to the second display 108. At any time, a user may close the applications folder 2910, e.g. by tapping an “X” icon shown in the folder.

Continuing with FIG. 29B, at 2918, the applications folder 2910 is opened on the second display 108, such as after a touch input has moved the applications folder from the first display 106 to the second display 108, or after touch inputs have closed the applications folder 2910 on the first display 106, and reopened the applications folder 2910 on the second display 108. The pinned applications that were previously on the pinned applications bar 2906 of the second display 108 are shifted to the pinned applications bar 2904 on the first display 106. Similarly, a touch input 2920 may be performed from right to left to shift content behind the applications folder 2910 on the second display 108 to the first display 106, as shown similarly at 2914. At 2924, while the applications folder 2910 is open, a touch input 2926 may move an application 2928 that is not currently in the applications folder 2910 into the folder 2910. It will be understood that pinned applications may also shift in response to the opening of an application on one display, and is not limited to the opening of an applications folder. Such behavior may allow the pinned applications to remain visible to a user.

In some examples, when no application or system component (e.g., folder) is open on either first display 106 or second display 108, a user may also shift the pinned applications that were on pinned applications bar 2904 on the first display 106 over to the pinned applications bar 2906 on the second display 108 through a right swipe/fling gesture, either within the pinned applications bar 2904 or a threshold area of pinned applications bar 2906. Similarly, the user may perform a left swipe/fling gesture either on pinned applications bar 2906 or pinned applications bar 2904 to shift the pinned applications that were previously on pinned applications bar 2096 on the second display 108 over to pinned applications bar 2094 on the first display 106. This gives the user the control to launch whichever pinned application on the preferred display. It will be understood that the above examples, including any other windowing gestures described above, also apply to double landscape poses as well, and the described gesture directions are relative.

FIG. 30 shows an example method 3000 of operating a dual screen computing device. Method 3000 includes, at 3002, displaying one or more applications in a pinned applications bar on each of the first display and the second display. Method 3000 further includes, at 3004, receiving a touch input opening an application or folder on one of the first display and the second display. In response, method 3000 includes, at 3006, displaying the opened application or folder on the one of the first display and the second display, and shifting pinned applications on the one of the first display and second display to the other of the first display and the second display. For example, if a touch input opens an application on the first display, the pinned applications in the pinned applications bar on the first display may shift to the pinned applications bar of the second display. Likewise, if a touch input opens an application on the second display, the pinned applications in the pinned applications bar on the second display may shift to the pinned applications bar of the first display. It will be understood that this may also apply when opening an applications folder, as described in regard to FIGS. 29A-B.
